The short answer
No-start on the DIS line splits three ways: no power reaching the machine, a door the machine does not believe is shut, and a control that is locked or waiting on something. Working them in that order takes a few minutes and settles most cases before any panel is removed. This is a compact family, so the ranking below is drawn from how these particular machines are put together rather than from the brand at large.
What you observe on these models
- The panel is completely dead — No lights, no beep on a button press — the machine is not being powered, and nothing inside it is the suspect yet.
- Lights come on but the cycle never begins — Power is present and the control is alive; the machine is waiting on a condition it has not been given.
- The start button beeps and nothing happens — The command was accepted and then abandoned, which usually points at the door interlock rather than at the button.
- A delay-start or lock indicator is lit — The machine is doing exactly what it was told. This is the single most common no-start that is not a fault at all.
- NEAR MISS — it runs but the water never heats — That is a heating fault, not a starting fault, and it belongs on a different page.
Causes, most likely first on the DIS line
- Door latch or interlock switch not made — First, and the cheapest to rule out. It ranks first because the latch takes mechanical wear every day, and because a cabinet or a hinge that has settled will hold the door a millimetre out.
- No power reaching the machine — Next most likely on these models. A dead panel is not a dishwasher fault until power has been proved at the machine — a tripped breaker or a switched spur is far more likely than a failed control.
- Starts but stalls with no water arriving — Third — worth checking once the two above are clean. The supply valve under the sink gets closed during other plumbing work and not reopened.
Check in this order, and why
- Close the door deliberately and listen for the latch — It should click home with light pressure. If it needs a shove, or the door sits proud at one corner, the interlock is the suspect and nothing else needs testing yet.
- Prove power at the machine, not at the wall — Check the breaker, then the switched spur or socket the machine is fed from — often inside the adjacent cupboard — and confirm it is on before assuming anything about the appliance.
- Confirm the supply valve under the sink is open — Start a cycle and listen for fill within the first minute. Silence where water should be running means the machine stalled rather than failed to start.
Before you open anything
Safety
Switch the machine off at its breaker before a panel comes off or a hand goes into the sump — a capacitor can hold a charge after the power is off. Shut the supply valve under the sink before disturbing a fitting, and never wedge the door interlock to watch a wash run.

When to call a technician
Latch, power, control lock and the supply valve are all owner checks and they cover most no-starts. The call begins when the panel is dead with power proven at the machine, or when the door latches correctly and the machine still refuses — those need metering inside the base. Call rather than experiment if you have found scorching, a burnt smell, or a breaker that trips the moment the machine is switched on.
